基于灰色关联分析与层次分析法的LNG工厂冬防保温
|
摘要
LNG工厂是低温工程与储运工程的结合体,具有工艺流程复杂、仪表测控点繁多、设备设施管理任务重等特点,故其冬防保温工作极为重要。以昆仑能源黄冈LNG工厂为例,根据历年的天气记录、维修记录、冬防保温方案等相关数据及资料,运用灰色关联分析与层次分析法,分别对停工与生产两种工况进行分析,制定不同工况下的冬防保温方案:运用层次分析法,结合天气情况,对停工工况进行分析,科学制定冬防保温方案,全面保护LNG工厂设备;运用灰色关联分析法,对正常生产工况进行动态分析,得出人力资源与物料成本最省的冬防保温方案。以上方案可为其他LNG工厂的冬防保温工作提供参考,但具体运用时应根据LNG工厂自身工艺特点及其所在地自然环境进行适当调整。
LNG plant is the combination of low temperature engineering and storage & transportation engineering, and it is characterized by complex process, various instrument inspection and control points and heavy equipment management, so its thermal insulation in winter is quite important. In this paper, Huanggang LNG Plant of Kunlun Energy was taken as an example. Its two working conditions, i.e., shutdown and production, were analyzed by means of grey correlation analysis and analytical hierarchy process based on weather record, maintenance record, winter insulation scheme and other related data over the years. And the winter insulation schemes for different working conditions were prepared. It is shown that analytical hierarchy process, together with weather change is applied to analyze the working condition of shutdown, formulate the winter insulation scheme scientifically and protect the equipment of LNG plant overall. Grey correlation analysis is adopted to dynamically analyze the working condition of normal production and prepare the winter insulation scheme whose human resource and material cost are the minimum. These schemes can be used as the reference for the winter insulation of similar LNG plants, but during the concrete application, they shall be adjusted appropriately based on the technological characteristics of the specific LNG plant and the natural environment where the LNG plant is located.
